Built on precision. Driven by technology. Trusted by builders across New England.
Our Story
Alpha Centauri Link was founded with a single mission: to bring enterprise-level technology integration to homes and commercial properties across New Hampshire and Massachusetts.
We saw too many projects where low-voltage work was an afterthought — cables jammed through walls, systems that didn't talk to each other, and homeowners left without documentation or support. We set out to change that.
Every project we take on is treated with the same rigor we'd apply to a data center: clean runs, proper terminations, full documentation, and systems that actually work. From pre-wire on new construction to full smart home integrations, Alpha Centauri Link is the low-voltage partner builders and homeowners rely on.
Our Values
Precision First
We plan before we pull cable. Every project gets a design review, material list, and schedule before a single hole is drilled.
Full Transparency
Itemized quotes, clear timelines, and as-built documentation on every job. No surprises.
GC-Friendly
We show up on time, communicate clearly, and finish clean. Because your reputation is on the line too.
Service Area
We serve a broad corridor from the Seacoast of New Hampshire down to Greater Boston. For larger commercial projects, we travel statewide and into Maine.
